l HINGE.

Specification of Letters Patent.

Patented Aug. 21 1 906.

Application filed May 27, 1906. Serial No. 262,561.

To all whom, it muy con/cern,.-

Be it known that I, FRANK ELLswoRTn SPRAGUE, a citizen of the United States, and a resident of Nashua, in the county of Hillsboro and State of New Hampshire, have invented a new and Im roved Hinge, of which the following is a fuil, clear, and eXact description.

This invention relates to hinges; and it consists, substantially, in the details of construction and combinations of parts hereinafter more particularly described, and pointed out in the claims.

The invention has reference more especiall to butt-hinges for swinging doors and the ike; and one of the principal objects of the same is to overcome numerous disadvantages and objections attending the use of many other contrivances hitherto devised for a similar purpose.

A further object of the invention is to provide a hinge of the character referred to with means for preventing the usual fasteningpin for the joint between the members thereof from working upwardly or out of place during the swinging movements to which such members may be subjected in use, thus overcoming any unsightliness in the appearance of the hinge and tending in large measure to prevent separation of the members thereof.

A still further object is to provide a hinge of this kind which is simple in construction and comparatively inexpensive to manufacture, besides being exceedingly strong and durable and possessing the capacity for long and continued service.

The above and additional objects are attained by means substantially such as lare illustrated in the accompanying drawings, in which- Figure 1 is a sectional view in detail, showing the application of my improved butthinge to a swinging door and support therefor. Fig. 2 is a plan view of the hinge with the members thereof straightened out, by which to more clearly indicate the construction and organization of parts. Fig. 3 is a vertical sectional view on the line 3 8 of Fig. 2. Fig. 4 is a horizontal sectional view on the line 4 4 of Fig. 2, the two members of the hin e being in open relation to each other; an Fig. 5 1s a similar view showing the two members of the hinge as closed to ether.

Before proceeding with a more etailed descrlptlon 1t may be stated that in the form of my improvements herein shown I employ a butt-hinge of special construction, combined with which is a fasteningin of special construction, special means iieing employed in connection with said pin for preventing the same from working out of place when the two members of the hinge are in closed relation to each other, said means being adapted to be carried into such relation with the pin as also to prevent the same from working out of place when the two members of the hinge are in open relation to each other. While I have herein represented m improvements in a certain preferred embo iment, it is to be understood that l am not limited thereto in precise details, since immaterial chan es therein may be resorted to coming witfiin the scope of my invention.

Reference being had to the accompanying drawings by the designating characters thereon, 1 and 2 represent the two members of an ordinary butt-hinge, the member 2 having rigid with the inner edge thereof a sleeve or tubular section 3, the ends of which terminate short of the upper and lower edges of the said hinge member, and the member 1 of which hinge has integral with the inner edge thereof the upper and lower sleeves or tubular sections 5 and 6, the bores or open-` ings of which coincide with the bore or opening in the said sleeve or tubular section 3 of the hinge member 2. (See Fig. 3.) As is usual with many forms of hinges of this character, the lowermost sleeve or tubular section 6 of the hinge member 1 is provided with a short stub-pin 7, which is practically rigid with said section and provided with an ornamental head 8, so as to assist in Yliving a finished appearance to the complete linge.

About centrally of the height of the sleeve or tubular section 3 of the hinge member 2 the sides of said section have formed therein a slot E), extending practically all the way through the section or to the inner edge of the hinge member 2, with which it is formed, and inserted within said slot is any suitable device adapted to permit of the insertion Within the alined tubular sections of the two hinge members (in the open position of said hinge members) of a fastening-pin l() and also adapted. in the closed` position of the hinge members with relation to each other to effectively engage with a part of the said fastoning-pin 1U in such manner as to prevent the latter from working upwardl in the closed position of the hinge mem er when IIO the hin re is employed on a swin ing door 11 or the ike. As herein shown, I preferably form the fastening-pin 1() with a reduced d1 ameter at 12, or, in other Words, I form an annular groove within the pin at the part of its height corresponding to the hei ht or location ol the slot 9 in the hereinbe ore1nentioned centrally-disposed tubular section 3 of the hinge member 2, and previous to the insertion of the pin within the alined tubular hinge-sections referred to I insert within the slot E) a metal disk or plate 13, having an opening 14 therein of a diameter slightly in excess of the larger' diameter of' the said fastening-pin 1t), thus permitting the latter to be passed through said opening, the said disk or plate being formed at one side of the said opening therein with an eccentric portion 15, projecting from which is a short tongue 16, it being here mentioned that the upper end of the fastening-pin 10 is also provided with an ornamental head 17, corresponding to the head 8 of the stub-pin 9 hereinbefore referred to, thus imparting symmetry to the general form and appearance of the hin e at the joint. As thus constructed it wil be seen that whenever the hinge members 1 and 2 are carried to closed relation with each other the edges of the eccentric portion 15 of the disk or plate 13 lying on either side of the tongue 16 will be movably engaged by adjacent portions of the inner edges o the said hinge members 1 and 2 in such manner as to cause the disk or plate to move inwardly, and thereby be partially received within the groove 12 of the fastening-pin 10, thus locking the latter in such manner as to eectually prevent it from working up from any cause whatever, as and for the purpose already explained. On carrying the hinge members 1 and 2 outwardly from each otherwas, for instance, on opening the door on which the hinge may be employedit does not follow that the disk or plate 18 is caused to be again moved outwardly to free the same from its engagement with the fastening-pin 1U, and consequently the device may be said to be equally effective in preventing the fasteningspin from Workil 1g upwardly when the hinge members are spread. apart. Should it be desired to remove the fastening-pin, however, it will be understood that it is necessary to move the disk or plate 13 outwardly after swinging apart the hinge members 1 and 2, thus to separate the disk or plate from its engagement with the fastening-pin and to bring the opening in the disk or plate into concentric relation with the bores or openings of the alined hinge-sections 3, 5, and 6.

It is thought that from the foregoing the construction and operation of my improvements will be fully miderstoml without ,further detailed description and also that the advantages thereof will be apparent to those skilled in the art to which the i1nprovements relate.

Instead. of forming the slot J in the tubular section 3 ol the hinge member 2 of the hinge it may be formed in either ol the tubular seetions 5 or (i of the hinge member 1, in which case the groove in the fastening-pin will he located in corresponding position and the device 13 as well7 as will be apparent.

Ilaving thus described my invention, I claim as new and desire to secure by Letters PatentW 1. A butt-hinge, comprising a plurality of members provided with intercngaging tubular sections, a fastening-pin having an annular shoulder and traversing the tubular sections, and means for engaging the shoulder to prevent the pin from working out of the sections, embodying a slidable plate having therein an opening through which the pin extends.

2. A butt-l'iinge, comprising a plurality of' members provided with interengaging tubular sections, a fastening-pin having an annular shoulder and traversing the tubular sections7 and means for engaging the shoulder to prevent the pin from wor ring out of the sections, embodying a slidable plate formed with an eccentric portion and having therein an opening through which the pin extends.

3. A butt-hinge comprising a plurality of members provided with interengaging tubular sections, a fastening-pin traversing the tubular sections, and. provided with an annular shoulder, and means for engaging the shoulder to prevent the pin from working out of said sections, embodying a slidablc plate having an eccentric portion and a projecting tongue, and formed with an opening through which the pin extends.

4. A butt-hinge, comprising a member provided at its inner edge with a centrally-disposed tubular section having a horizontal slot cut therein another member having tubular sections alining with the ends of the said section, a fasteningpin extending through all the sections and having an annular shoulder thereon., and. a plate havin(i a hole for receiving the pin loosely mounte in the slot for engaging the shoulder.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
